Speci'cation of Letters Patent.

Application led January'ZO, 1-909. Serial No. 473,364.

To all wilma it may concern.'

Be it known that l, ANTHONY LOHMAN, a citizenof the United States, and a resident of Philadelphia, inthe county of Philadelphia' and State of Pennsylvania, have invented a certain new and useful Ozonizer, Of which the following' -is4 a specification.

The principal object of the present invention is to provide' an efficient, simple and comparatively ineX' ensive ozonizer and one in which the die ectrics which are made of micanite can, in case, of accident, bel readily removed and-replaced `without materially disturbin the setting or device. The invention wil be claimed at the end hereof, but will rst be described in connection with the embodiment of it chosen for illustration in the accompanying drawings, in whichv Figure 1, is a sectional View of the complete device. Fig. 2, is an elevational view, partly in section, drawn to an enlarged scale and illustrating one ofthe ozonizers detached from the setting. Fig. 3,' is a section on the line 3-3 of Fig. 2, and Fig. 4, is an end view of the device shown in Fig. 2.

In the drawings 1, is a casing or shell having near its ends tube sheets 2 and 3, which divide it into a central Water .chamber and end air chambers. The heads a, either or both, of the casing 1, are removable as for repairs.

4 and 5, are induct-ion and eduction connections for the Water and 6 and 7, are induction and eduction connections for the air chambers. I

8, is an open ended tube of electrically conducting material and a numbei` vof these tubes are shown as arranged in the `Water chamber in communication with' the air chambers and they aremounted'through the'tube sheets 3 with their ends exposed therefrom.` These tubes ,are permanently connectedsvith the tube plates and make a tight joint Where they pass through the same.

9, are iianged caps' having perforated heads.`

10, is a hollow cylindrical. electrode or discharger; it is attached to and supported by the caps 9, as shown by means of a rod 11, which passes through the caps and through the hollow 'electrode 10.

This rodl is shown asheld to place by means of nutsl 12 and 13. The rod serves to'support the electrode. 10'in proper relation -with respect to the caps, that isvusually, axially thereof'. 1 4-, is a dielectric consisting of a tube of micanite, to the ends of which the flanges 'of the caps are fitted. The rims of the. caps T he caps 9, are of insulating material as pore celain or the like, so that theelectrodes 10 are insulated. 16, is a conductor in electric-al connection with the tubes 8 or some part in electrical connection therewith and these connections 15 and 16, are connected to an appropriate source for example, the connection 16 to ground and the connection 15 to one side of the secondary of a transformer, the other side of which is grounded.

ln use Water keeps the tubes cool and air or other substance to be electrified or ozo nized passes through the openings in the caps 9 and between the smooth outer surface 0f the electrode 10 and the smooth inner surface of the tube S. There is a discharge between these smooth inner surfaces and through or past the dielectric 14, so that the desired result is obtained. In the event of an accident to the dielectric, one of the heads a., is removed and thereupon the dielectric .can be readily replaced by removing one of the nuts 13 and 'withdrawing the adjacent cap and injured dielectric and then replacing the saine with a new micanite. During this operation the apparatus or setting is not materially disturbed and the change can be quickly made.

lVhat l claim is:

,1. An ozonizer comprising a casing having near its ends tube sheets which divide it into 1 a -central Water chamber and end air cham- .bers induction and Kediction connections for said chambers, anv open ended conducting ltube arranged in. .the wat-cr chamber and communicating With said air chambers and iiXedthrough said tube sheets With'its ends exposed therefrom, a micanite dielectric detachedfrom said tube and arranged therein, a hollowl cylindrical discharger arranged within the dielectric, flanged perforated caps detachably'applied to the ends of the dielectric and abuttin on the ends or said tube, means -for detac and .discharger and' electrical connections to the discbnrger and tube, substantially as described.v

2*; An ozonizer comprisingv a cylindrical.

'forate discharger arranged. within the dielectric and E{,)rovided at its ends -vfith inens for detacha ly engaging said caps, and electrical 1connectionsffor said t1;1li1e-and-.dis-

charger, substantially as described.

3. 'In an ozoni'zer the combination oan exterior imperforate casing constituting onel electrodeZ an interlor-im erforate diseharge'i1 constltutlng the other e ectrode, a dielectric ably connecting the caps,

Aconsisting of shell arranged between said artsand independent of and detachable roin each/and insulating caps for detach* ably supporting said arts in pro )er relative positions, substantie y as descri ed.

4. An-ozonizer comprising a conducting ilnperforate tube having a sinoothint'erior surface, a Inicanite tubular dielectric ai'-l rangedrin and independent of and `detachable from said tube with its ends pro'e'ctin .'ther'efroni, flangedy caps having f er orate ends litted to the ends of the .die ectricand 'abutting on the ends of said. til-be, la rod pene- 'trating'tlie central d'portions of said caps and havingthread an nutv c'ezfinectionsy there;

1with, and a hollow irnperforated cylindrical. discharger mounted on lsaid rod, substan- .tially'as described.

.In testimony whereof l have hereunto 'signed my naine.
